Patton John Oswalt (born; January 27, 1969) is an American stand-up comedian, writer, actor and voice actor known for roles such as Spencer Olchin in the sitcom The King of Queens and for voicing Remy in the film Ratatouille.

Oswalt first began performing stand up comedy in the late 1980s or early 1990s, by his own reckoning.[12] After writing for MADtv and starring in his own 1996 comedy special for HBO, he went on to garner notable roles in films and television shows.[13] His most prominent and long-running role was as Spence Olchin on The King of Queens.[14] His first starring film role was as the voice of Remy, the lead character in the 2007 Pixar film Ratatouille.[13] He has also appeared in smaller roles in such films as Magnolia[13] and 22 Jump Street.

In 2009, Oswalt played Paul Aufiero, the leading role in Robert D. Siegel's 2009 directorial debut, Big Fan. He was to star in a 2010 Broadway revival of Lips Together, Teeth Apart.[19] However, the show was postponed then eventually canceled due to Megan Mullally's departure from the production when the director denied her request to replace Oswalt due to his lack of stage experience.[20]

He starred in the Showtime drama The United States of Tara as Neil, an employee of Four Winds Landscaping.[21] He also provided the voice of Thrasher, a robot protagonist from the Cartoon Network show, Robotomy.[22]

In January 2011, Oswalt released his first book, Zombie Spaceship Wasteland.[23]

As of September 2013, Oswalt narrates the TV series, The Goldbergs.[25] He also had a recurring role as Constable Bob Sweeney in the fourth season of the FX series Justified.

As of March 20, 2014, it was announced that Patton would be cast in the role of Agent Koenig on the TV series Agents of S.H.I.E.L.D. He later appeared in separate episodes as brothers Eric and Billy Koenig. He will continue to appear in the second season as Billy and a third brother Sam (as the original brother Eric is now deceased).

In January 2015 Oswalt's memoir Silver Screen Fiend: Learning About Life from an Addiction to Film was published by Simon & Shuster.

Oswalt's stand up comedy covers topics ranging from pop culture frivolity such as comic book supervillains and 1980s glam metal to deeper social issues like American excess, materialism, foreign policy and religion. He also discusses his atheism in his stand-up. On February 28, 2009, Oswalt recorded his third comedy album at the Lisner Auditorium at George Washington University in Washington D.C. It premiered on Comedy Central as Patton Oswalt: My Weakness is Strong on August 23, 2009, and was released on DVD August 25, 2009.[26]

Oswalt's album, Patton Oswalt: Finest Hour, was released on September 19, 2011. The extended and uncensored DVD of this special was released in April 2012, a few days after its television premiere on Comedy Central.[27][28]

Patton's newest comedy special Tragedy Plus Comedy Equals Time was to be released on January 16, 2014 via online movie streaming website Epix but was pushed back by the company for unknown reasons.[29] However, it did premiere on Comedy Central on April 6 and became available for purchase on April 8 in both DVD and CD format.[30]
